About this item

• Low-Power Means Longer Battery Life: Because of the low power consumption, YoLink Garage Door Sensor's batteries may last 5 years or more (depending on application and device usage/activity), on standard AAA Alkaline batteries (lithium batteries not required)!
• World's Longest Wireless Range: Powered by LoRa technology, the long-range yet low-power system offers the industry’s longest receiving range in the market (1/4 mile). Our long-range coverage enables its use in areas challenging for most residential Wi-Fi systems, such as basements, outdoor porch/patio areas, sheds, free-standing garages, even remote outbuildings on your property.
• Universal: Easy-to-add functionality to upgrade your existing garage door opener. Compatible with door openers manufactured after 1993 that utilize photoelectric sensors; Please check compatibility at the description before purchase
• Early-Warning Notifications: Receive real-time early-warning notifications in the form of smartphone banner alerts, limited SMS/text messages, and emails, each optional and configured per your needs. Please note: YoLink Garage Door Sensor does not alarm or chime, it only sends notifications; For an audible alarm, consider our Siren Alarm
• Doesn't Function without YoLink Hub: YoLink Hub serves as the primary controller for YoLink devices, enabling connection to the internet and the cloud.
